1 Approval Access to the Terminal and the Station is only authorised for Carriers, Drivers and Roadway Equipment all of which have been Approved in advance by the Terminal's Operator according to the procedure described below. Approval does not imply the Terminal's Operator's assent to the Approved element but must be considered as authorisation to use the Station.

1.1 Stages in the Approval procedure

1.1.1 Requirements and information For each element (be it a Carrier, Driver, or each item of Roadway Equipment), the Terminal's Operator specifies:

a. The minimum requirements to be met b. Possibly, recommended good practices, encouraged but not critical for Approval c. The list of documents and information to provide when requesting Approval.

The Client is responsible for ensuring that each element meets these requirements, at the time of Approval and for all subsequent Scheduled Operations. The Terminal's Operator reserves the right to carry out checks in situ and/or demand documents in connection with these requirements at any time.

1.1.2 Request for Approval and exchanges of information The Client sends a Request for Approval to the Terminal's Operator's contacts listed in the Specific Conditions. The request must be sent at least ten (10) Business Days before any request for Scheduling an Operation (including a Test Loading) involving the element to be Approved. All the required documents and information must be attached to the request and if necessary translated into French or English. The Terminal's Operator makes reasonable efforts to respond swiftly to the request. If there are too many requests, the Terminal's Operator may ask the Client to prioritise its requests on the basis of the planned dates of the Operations. The documents and information to be sent to the Terminal's Operator with the Request for Approval are listed below for each element requiring Approval.

1.1.3 Compatibility analysis On the basis of the documents and information provided, the Terminal's Operator ascertains that element requiring Approval meets the requirements set out below. If necessary, the Terminal's Operator or the Client may request a meeting in order to obtain more information, which must be attended by at least one representative of the Client or Carrier.



If several items of Roadway Equipment are identified as being Sister Trucks, i.e. identical in terms of manufacturer, design and model, operate by the same Carrier and having the same technical documentation, the Terminal's Operator may, at the request of the Client, agree to do the compatibility analysis in one go for all the items of Roadway Equipment concerned. However, each item of Roadway Equipment must undergo a Test Loading separately to be duly Approved. The Terminal's Operator sends the Client a response to the Request for Approval as soon as possible, which may be:

a. Negative: the element is incompatible, b. Provisional: requesting additional documents or further information, c. Positive:

i. For a Carrier, this allows it to move directly on to the validation stage explained in detail in Article 1.1.5 below,

ii. For a Driver or item of Roadway Equipment, this allows it to move on to the next stage, namely a Test Loading.

1.1.4 Test Loading A Test Loading is like a normal Loading, during which the Terminal's Operator carries out additional checks on the Driver and the Truck. A Test Loading must be Scheduled in a Slot authorised in advance by the Terminal's Operator (usually during working hours on a Working Day), who where necessary will specify all the conditions to be met for Scheduling the Operation. The Client must specify the condition of the Tank Container requiring approval (for instance: in gas or in nitrogen, etc.). When the Slot has been confirmed by the Terminal's Operator, it must be duly Scheduled in the Scheduling Tool by the Client. The same Test Loading can Approve both a Driver and a Truck (complete). With the prior consent of the Terminal's Operator, who will specify the number of Slots to plan for, the Test Loading can be combined with a Cooling Down, gassing up or other Service. The Driver must present himself with his Truck ahead of the time scheduled for the Slot, this lead time being specified by the Terminal's Operator according to the number of elements requiring Approval and the type of Operation. This Test Loading is the subject of an observation report sent to the Client, identifying any corrective measures that may need to be taken. If the Test Loading is inconclusive, depending on the difficulties encountered, the Truck may be required to leave the Terminal empty or only partially loaded. 1.1.4.1 Test Loading for a Driver The Terminal's Operator carries out the following checks:

a. Conformity of the Driver with the documentation provided b. Command of the language (French or English)



c. Conformity of the PPE d. General knowledge (conversation with the Officer and a written test):

i. Safety rules at the LNG terminal ii. Basic characteristics of LNG

iii. Risks iv. ADR and GCW (Gross Combination Weight) v. Documents

vi. Operation and characteristics of the Tank Container vii. Station operation

viii. Sequence of operations (including traffic plan) ix. Security Protocol defined with the Carrier (given to the Driver)

e. Skills and know-how tested in situ around a Truck. 1.1.4.2 Test Loading for Roadway Equipment The Terminal's Operator carries out the following checks:

a. Conformity of the Roadway Equipment with the documentation provided b. Authenticity of the ADR plate c. A check that the piping and instrumentation diagram (PID) matches the facility and the

identification of the valves d. Emergency stop tests e. Compatibility of the connection to the Station's air system (LARCO type system where

applicable) f. Test of the mechanism preventing the vehicle from moving while connected to the

Station’s facilities g. ADR conformity (condition of the Truck, lights, signals, chocks, fire extinguishers, etc.) h. Absence of leaks (all fluids)

1.1.5 Validation On the basis of an analysis of the documents and information received and the results of a Test Loading carried out by the Terminal's Operator:

a. The element is not authorised to perform operations at the Station; the entire procedure must be completed again for any new request for Approval of the element in question,

or b. The element can undergo another Test Loading after the corrective measures

identified in the previous stage have been taken; or or

c. The element (Carrier, Driver or Roadway Equipment) is Approved and authorised to carry out all operations at the Station; in which case the Client receives a signed certificate of Approval for each element separately.

A certificate of Approval is usually valid for five (5) years. In certain special cases, the certificate of Approval may mention restrictions (for instance: compatibility limited to a single Terminal). In the absence of any restrictions stated in the



certificate, the certificate of Approval for an item of Roadway Equipment is deemed valid for all the Terminals. The certificate of Approval for a Driver is valid for all the Terminals but when he/she goes to a Terminal for the first time, the Client must notify the Terminal's Operator thereof and the Driver must follow an induction session, comparable to a simplified Test Loading, to familiarise himself with the Terminal's specific equipment and procedures. The Terminal's Operator may issue the Driver with a personal access badge to keep, and may fit an automatic recognition system on the Roadway Equipment (such as an RFID chip or QR code) to facilitate reception at the Terminal.

1.1.6 Follow-up The Client must ensure that the Carrier renews the authorisations and certificates as often as regulations so require and send the Terminal's Operator the new versions of the documents without undue delay. An Approval may be suspended by the Terminal's Operator without prior notice in the event of a serious incident involving the Carrier, Driver or Roadway Equipment, a serious breach of rules and procedures, or even a spot check revealing a Driver's lack of knowledge of the rule and procedures. In that case, the Terminal's Operator shares its analysis of the incident with the Client and explains the measures taken or under consideration. The Client informs the Terminal's Operator of any significant changes, and the latter will then decide whether the change requires the Approval procedure to be repeated. If an Approved Driver or item of Roadway Equipment changes Carrier (occupational mobility, assignment), the certificate of Approval remains valid with the caveat that:

a. The Terminal's Operator is informed as soon as possible b. The new Carrier is itself Approved and in conformity c. For an item of Roadway Equipment, no modification has been made to it.

Once the Approval certificate has expired, the Client must complete the Approval procedure again.

2 Scheduling

2.1 Use of the Scheduling Tool The Operator grants the Client several licences to access the Scheduling Tool. If the Client requests additional licences and the Operator is able to grant them, it may invoice the Client for any extra costs in that respect subject to producing supporting documents. The Operator may temporarily withdraw licences if the Client has not loaded a Tank Container within one hundred and eighty (180) days. The licences will be reassigned to the Client when it Schedules a Tank Container. The Client may grant a third party (for instance a Carrier) permission to use one or more of its licences but remains at all times fully responsible for all actions carried out with these (for instance, the Client will assume the consequences of any belated cancellation or Abusive Scheduling done by the third party). These licences remain in the name of the Client and grant access to all the Client's information in the Scheduling Tool.

2.2 Slot times Operations must be Scheduled by the Client at the times of the Slots displayed in the Scheduling Tool.

2.3 Preparation and modification of the Scheduling The principle of Scheduling is to allow the planning of Operations in complete safety by optimising the Station's capacity while granting fair access to all the Users. Barring temporary arrangements made by the Terminal's Operator, Slots are awarded on a "first-come, first-served" basis. For the sake of convenience, the Scheduling Tool may display Slots in calendar days without this in any way affecting the applicability of the Contract. The mains parameters of the Scheduling Tool are as follows:

a. Availability lead time of Slots: fourteen (14) calendar days before the day of the Slot (D+14)

b. Slot availability times: every Day from ten (10) a.m. c. Time from which a cancelled Slot will be invoiced: every Day at three (3) p.m. for any

Slots on the following Day. The Terminal's Operator can modify these parameters subject to notifying the Client thereof. The Client fills in or checks the required fields for each Slot it Schedules, in particular:

a. Terminal b. Slot Date and time c. Client and Contract d. Carrier



e. Driver f. Tank container g. Quantity of LNG to load: the Client must specify a target quantity, or failing which

select "max" if it wants the Tank Container to be fully loaded subject to regulatory constraints (ADR and GCW in particular)

h. Requested services (Loading, Cooling Down, etc.) Any specific information concerning the Operation must be provided by the Client. For a straightforward Loading (excluding a Test Loading, Cooling Down or any other Service), and in the absence of any incident, failure or Case of Force Majeure, the Terminal's Operator undertakes to complete the Operation within a period of one (1) Slot. For any Service other than a straightforward Loading, the Client is responsible for Scheduling the right number of consecutive Slots needed for the Operation it wishes to plan. If in doubt, the Terminal's Operator may give a non-binding estimate (in particular for long Operations like Cooling Down, gassing up or inerting). If there are not enough Scheduled Slots and the Officer realises that the Operation cannot be completed within the allotted time, the Terminal's Operator reserves the right to interrupt the Operation. When the Scheduling is confirmed by the Client, the Slot becomes unavailable for other Users and the Client is committed to using and paying for it, unless it cancels it within the deadline specified above. On confirmation, the Booking Single Code (IUR) is issued by the Scheduling Tool. The Driver must be able to present at least the last 4 characters of the Slot's IUR on arrival at the Terminal and at any time during the Operation. The Client loses priority over a Slot it has Scheduled if it cancels or postpones it.

2.4 Delay and rescheduling The Terminal's Operator is only required to carry out Scheduled Operations if the Truck arrives no later than ten (10) minutes after the beginning of the Scheduled Slot. After which time, the Terminal's Operator notifies the Client that the Operation has been refused and asks the Client to postpone it to an available Slot on the same Day or possibly to the Reserved Slot, subject to it still being available. If no Slot is available on the same Day, and the Reserved Slot is not available either, the Operation is deemed to be cancelled by the Client. If a delay is caused by the Terminal's Operator, even further to a short-lived case of Force Majeure, it will endeavour to resume the Scheduling in the initial order, informing the Client of the delay, the expected length of time needed to return to normal and any Operations that cannot be carried out, the Client having the option to adjust this order according to its



priorities. The Terminal's Operator shall make reasonable efforts to offer Reserved Slots in order to minimise the impact on the Client's Operations. Certain operations concerning other Terminal activities may force the Terminal's Operator to postpone or cancel a Slot. As a Prudent and Reasonable Operator, the Terminal's Operator makes every effort to avoid or minimise the impact of postponed or cancelled Slots on Station availability, and where applicable update the Scheduling Tool at the earliest possible opportunity. If the Slot concerned is already Scheduled by the Client, the Terminal's Operator informs the Client at the earliest possible opportunity in order to enable it to find a replacement Slot.

2.5 Abusive Scheduling The flexibility offered by the Scheduling Tool must on no account allow the Client to prevent other users from accessing the Station. The Terminal's Operator reserves the right, after having notified the Client, to change the Scheduling in the event of proven Abusive Scheduling.

2.6 Congestion and downgraded mode In the event of congestion (very busy Station and lack of available Slots), the Terminal's Operator may take any necessary measures, including modification of Slot availability times, deadlines for invoicing belated modification or cancellation, to achieve the following objectives:

a. Allow fair access to the Station for all Users b. Abide by the "first-come, first-served" principle

If the Scheduling Tool is unavailable, the Scheduling is done by any means agreed on by the Parties.

3.2 General rules Trucks must not park in the area around the Terminal, either before or after the Operations. There are ADR truck parks near the Terminals. All Trucks must be able to quickly leave the area around the Terminal if the need arises and must not be left unattended. Barring security imperatives, the trailer must not be unhitched. For all Operations, movements and manoeuvres in or in the immediate vicinity of the Terminal, the Driver is placed under the supervision of the Terminal's Operator and must obey all safety instructions issued by the Officer or the Terminal's Operator's staff or the security guards. All Operations at the Station takes place under the responsibility of the Officer. The Driver must assist the Officer throughout the operation. Barring any provisions to the contrary for certain specific loading stages, specified below in the description of the sequence of Operations, the Officer is responsible for handling the Station's equipment and the Driver is responsible for handling the Roadway Equipment.

3.3.2 Station controls and access clearance The Terminal's guardhouse and security guards admit the Driver and the Truck and clear them to access the Station in accordance with the Scheduling. On arrival, the Driver must park his Truck in the designated areas and present himself at the guardhouse. He/she must be able to present:

a. His identity papers and ADR permit b. His personal access badge, if one was issued to him at the time of Approval c. The identification of the Roadway Equipment and approval certificates d. The automated recognition device (RFID chip or QR code), if one was fitted to the

Roadway Equipment at the time of Approval e. The IUR of the Scheduled Slot f. The waybill specifying his destination (place of delivery)

The security guard checks that:

a. The documents are authentic and currently valid b. The Driver and Roadway Equipment are duly Approved c. The IUR is valid and consistent with the Scheduling d. The time of arrival is consistent with the Slot's times

The security guard may also be led to search the Driver and/or the Truck's cab, only for security purposes. Non-ATEX devices (mobile phones, etc.) must be left at the guardhouse, in accordance with the site's instructions. The security guard or the Officer (if he/she goes to the guardhouse) uses a checklist to ascertain that:

a. The Truck and its equipment are in good working order and do not present any visible defects like a broken indicator, a punctured tyre, defective heat insulation (condensation on the external container), …

b. The Driver has his PPE, which is in a good state of repair



c. The LNG Safety Data Sheet (document issued by the LNG vendor specifying the data needed to handle the LNG in complete safety) and the other documents required by current regulations are on board the vehicle.

When all the checks have been carried out, the security guard or the Officer, in coordination with the Terminal's control room, can authorise the Driver and Truck to access the Station. On the instructions of the security guard, the Driver proceeds to the Station.

3.4 Sequence of Operations

3.4.1 Verification of the condition of the Tank Container The Tank Container must meet the following conditions, otherwise the Operation may be refused by the Terminal's Operator:

a. Be under natural gas or nitrogen atmosphere (unless it has Scheduled a gassing up) and meet the following specifications (the Terminal's Operator reserves the right to carry out checks):

i. maximum 1 ppm steam H2O ii. maximum 100 ppm CO2

iii. maximum 100 ppm O2 b. Be “cold” (unless it has Scheduled a Cooling Down), i.e. in cryogenic conditions. The

measured temperature of the evaporations on depressurisation must not exceed a threshold set on each Terminal:


-80°C -30°C

c. Be equipped with seals and coupling in perfect working order and have spare seals if need be.

If the Tank Container is not cold without a Cooling Down having been Scheduled, the Officer normally refuses the Operation, but in exceptional cases, if Scheduling conditions so permit, it may agree to the Operation with the agreement of the Driver recorded on the checklist. In that case, the Terminal's Operator makes reasonable efforts to perform a Cooling Down, but the Operation may be interrupted by the Officer at the end of the Scheduled Slot, even if the Scheduled Service has not ended, and the Operator and/or the Terminal's Operator cannot be held liable for any damage caused to the Roadway Equipment as a result of the Tank Container not being in a good condition.

3.4.2 LNG Loading and/or Truck Cooling down The stages of the LNG Loading and/or Cooling down Operation are as follows (the order of the stages may vary depending on the Terminal):

1) Position the Truck (chocks, immobilisation) 2) Make earthing connection 3) Connect the fluid and gas hoses 4) The Officer approves the mass to load 5) Weigh the unladen Truck 6) The Driver checks the correct configuration of the valves (bypass valves and vents

closed)



7) Decompress the Tank Container to roughly one (1) bar 8) Cool down the hoses and manifolds 9) Start the Cooling Down and/or Loading sequence 10) End of Loading 11) Empty and flush the hoses with nitrogen 12) Disconnect the hoses and the earthing connection 13) Weigh the loaded Truck 14) Edit the loading documents 15) The Truck leaves the Station and the Terminal

The Tank container's fill rate will be checked by the Officer during loading based on the Tank container's level. The Tank container's fill rate must comply with regulatory requirements (ADR and GCW in particular). The unladen weight, laden weight and mass of loaded LNG are determined using the Station's weighbridge, failing which the Terminal's. The pressure of LNG at the flange is controlled to remain lower than the opening pressure of the Tank Container's valves. The Terminal's Operator makes all reasonable efforts to ensure that the pressure in the Tank Container does not exceed one (1) bar on completion of Loading. Loading is done with the Station’s hoses. The Tank Container's hoses are not used and the Terminal's Operator on no account checks their conformity.

3.5 Issue of documents and departure from the Terminal On completion of the Operation, the Transport Document and a copy of the Loading Certificate are given to the Driver in provisional versions clearly identified as such. These documents ensure circulation in full compliance but must not be regarded as contractually binding documents, more particularly with regard to the quality of the LNG or the energy value of the cargo. The Client can also use the Scheduling Tool to consult these documents in their provisional version thirty (30) minutes after completion of the Operation. Only the final versions of the documents, updated in the Scheduling Tool and put at the disposal of the Client, must be regarded as approved by the Terminal's Operator. If a Loading Certificate is re-edited, only the latest version is deemed authentic.



4 LNG Quantity and quality calculation

4.1 Quantity of loaded LNG

4.1.1 Mass of loaded LNG The mass of loaded LNG is measured using a weighbridge at the Terminal that complies with the Measuring Instruments Directive and has undergone a metrological inspection under the supervision of an accredited audit firm. The Terminal keeps documents vouching for the metrological conformity of the weighing device(s). If the weighbridge is unavailable, or for any situation in which the weighbridge does not give a satisfactory measurement of the loaded LNG, the Terminal's Operator will use the Station's mass flowmeter, or if that is unavailable, he/she will define a fault-tolerant mode and notify the Client thereof. The mass (M) of loaded LNG, expressed in kilogrammes, is: 𝑀𝐺𝑁𝐿 𝑐ℎ𝑎𝑟𝑔é (𝑘𝑔)

= 𝑀𝐶𝑎𝑚𝑖𝑜𝑛−𝑐𝑖𝑡𝑒𝑟𝑛𝑒 𝑎𝑝𝑟è𝑠 𝑂𝑝é𝑟𝑎𝑡𝑖𝑜𝑛(𝑘𝑔) − 𝑀𝐶𝑎𝑚𝑖𝑜𝑛−𝑐𝑖𝑡𝑒𝑟𝑛𝑒 𝑎𝑣𝑎𝑛𝑡 𝑂𝑝é𝑟𝑎𝑡𝑖𝑜𝑛 (𝑘𝑔)

4.1.2 Volume of loaded LNG The volume (V) of loaded LNG, expressed in m3, is calculated using the mass (M) of loaded LNG and the mass density (ρ) of LNG at -160°C according to the following equation:

𝑉𝐺𝑁𝐿 𝑐ℎ𝑎𝑟𝑔é à−160 °𝐶 (𝑚3) = 𝑀𝐺𝑁𝐿 𝑐ℎ𝑎𝑟𝑔é (𝑘𝑔)

𝜌𝐺𝑁𝐿 à −160 °𝐶 (𝑘𝑔

𝑚3⁄ )

4.1.3 Energy of loaded LNG The energy E of loaded LNG, expressed in kWh, is the mass of loaded LNG multiplied by the mass GCV of the LNG using the following formula:

𝐸𝐺𝑁𝐿 𝑐ℎ𝑎𝑟𝑔é(𝑘𝑊ℎ) = 𝑀𝐺𝑁𝐿 𝑐ℎ𝑎𝑟𝑔é(𝑘𝑔) × 𝑃𝐶𝑆𝑚𝑎𝑠𝑠𝑖𝑞𝑢𝑒 (𝑘𝑊ℎ𝑘𝑔⁄ )

The energy of the loaded LNG thus calculated is used to deducted the inventory level of LNG held by the Client under its Access Contract or Loading Authorisation.

4.1.4 Equivalent in volume of loaded natural gas The equivalent in volume of loaded natural gas in m3(n) at 0°C with a pressure of 1.01325 bar is calculated using the volume of loaded LNG at -160°C multiplied by the LNG/natural gas expansion factor.

4.2 Quality of loaded LNG

4.2.1 Determining the composition of the loaded LNG The composition of the loaded LNG, expressed as a molar percentage (%mol.), is determined after vaporisation of the LNG by chromatography in gaseous phase in accordance with the ISO 6974 standard.



The sample of LNG used for these measurements is taken at the Terminal's generating point (regasification of the LNG for transmission to the gas transmission network) or at any other point deemed more precise by the Terminal's Operator. If no gas is transmitted at the Terminal, the Terminal's Operator will use the latest measurement data. If no gas is transmitted at the Terminal for a long time, the Terminal's Operator may propose a simulation of the changing characteristics of the LNG.

4.2.2 Calorific value, Wobbe Index, mass density and relative density calculations The main physical characteristics of the gas (volumetric calorific value (kWh/m3(n)), mass calorific value (kWh/kg), Wobbe index, density and mass density) are determined according to the ISO 6976 standard for a reference combustion temperature of 0°C and a volume measurement temperature of 0°C, both at an atmospheric pressure of 1.01325 bar.

4.2.3 Calculation of the density of the loaded LNG The density of the loaded LNG in kg/m3 is calculated using the composition of the loaded LNG in mole % at a fixed temperature of –160°C, taking into account the molar mass of each constituent as defined in the ISO 6976 standard, the molar volume of each constituent, correction factors K1 and K2 as described in the revised Klosek McKinley calculation method published in the Technical Note of NBS (National Bureau of Standards) in December 1980.
